[Example] editor.present_themed with embedded pyui loaded into a Custom ui.Viewbrowsing

Nothing ground breaking here. But in my mind at least it's a perfect example of having a embedded or is it imbedded pyui file in your source.
The gist Just displays a ui.View in a loop applying the built in themes. The view is displayed using wait_modal.
Not that it needs to be done like this, just one example. Of course the ui.View could have been done in code. Also no need to have it a part of a custom class. But in my mind, offers a more functional demo.
